Rainwater Tank Level Monitor
Rainwater Tank Level Monitor — ESP8266 IoT Kit with HC-SR04
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
You'll build a real-time monitor that measures rainwater tank depth with ultrasonic precision, displays the level on an OLED screen, and sends a daily summary and critical empty alerts to your phone — all powered by an ESP8266. This project combines physical computing with practical water management, making it a standout for home automation enthusiasts and students alike.
What You'll Build
A fully functional rainwater tank level monitor that displays the current water depth on an OLED panel. The system connects to your home Wi-Fi and sends a daily report via Telegram or email, plus an immediate alert when water falls below a critical threshold. You'll have a working prototype that can be installed in a small tank setup.
What You'll Learn
- How to interface an HC-SR04 ultrasonic sensor with ESP8266
- Programming Wi-Fi connectivity to send alerts over the internet
- Displaying real-time sensor data on an OLED screen using I2C
- Wiring and powering a standalone IoT device on a breadboard

Who This Kit Is For
CBSE Class 11–12 students building IoT projects, B.Tech ECE/EEE undergraduates exploring embedded systems, ATL Tinkering Lab innovators, Smart India Hackathon participants, and water‑conservation hobbyists. This kit is ideal for anyone who wants a guided, professionally supported build — whether for a school submission, a prototype, or home use.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to open your AI build companion, which knows this circuit and code. You can also reach us on WhatsApp for personal help within hours.
Can I use this kit to monitor a real rainwater tank?
Yes. The HC-SR04 works up to 4 meters, making it suitable for small to medium tanks. Just weatherproof the sensor and mount it above the tank's opening.
How are daily reports and alerts sent to my phone?
The ESP8266 connects to your Wi‑Fi and can push messages via Telegram or email using IFTTT webhooks. Code examples for both are included in the AI companion.
Is the kit programmable with the Arduino IDE?
Absolutely. The NodeMCU is programmed with the Arduino IDE, and all required libraries are pre‑listed in the build guide. No extra hardware needed.
HC-SR04 measures rainwater tank level. ESP8266 sends daily report and empty alerts.
